Here is a quick little video tip on connectors which can be found in Boundary Surfaces, Sweeps, and Lofts. Most users that utilize these features often are aware of the connector options available which can help you shape the surface (in particular the UV flow).
This tip shows how to utilize a single surface edge for multiple profiles in a Boundary Surface without having to create construction sketches. With the technique shown, you can also set limits for the use of connectors on edges. The model example is pretty simple since the part I used this tip on recently cannot be shown publicly.
Stay tuned, MUCH more to come!!
